During the investigation and observation of experts and scholars, more than 120 people, including directors of agricultural extension centers, main technical backbones and large growers in various counties and urban areas of Qujing City, and directors of comprehensive agricultural service centers, technical backbones and large growers in 27 townships (towns, streets) of the main potato producing areas in Xuanwei City, exchanged views with experts and scholars face-to-face, listened to and shared the scientific research results of experts and scholars.
In order to significantly improve the level of potato industrialization in Xuanwei City, promote the "National Potato Liangsheng Base County Construction" project to go deeper and more concrete, help rural revitalization, achieve complementary advantages, accelerate the selection, promotion and transformation of new potato varieties, and serve the high-quality development of agriculture. On the morning of July 7, Xuanwei City signed a joint research agreement on potato seeds in Xuanwei City, and xia Lihua, vice mayor of Xuanwei City, attended the signing ceremony.
Why do many experts and scholars, including the chief scientist of the national potato industry technology system, gather to Xuanwei? This has to start from the location advantage of Xuanwei City. Xuanwei is located in the northeast of Yunnan Province, the junction of Yunnan and Guizhou Provinces, Shuo has the reputation of "the first pass into Yunnan" and "the hometown of cloud legs". It is the most populous county in Yunnan Province and the only major grain producing county in Yunnan Province with an annual grain output of more than 1 billion kilograms and 1.6 billion kilograms, and has been commended by the Ministry of Agriculture and Rural Affairs for 13 consecutive years. In addition, Xuanwei is located in the center of the southwest potato industry belt, is one of the main potato producing areas in Yunnan Province, low latitude and high altitude, soil and climatic conditions are suitable for potato production, 900,000 mu of potatoes are planted all year round, and the sown area accounts for one percent of the country, one-tenth of Yunnan Province, and one-third of Qujing City. Third, the biggest feature of Sherwin-Williams potatoes is that they can be planted all year round, and fresh potatoes are on the market every anniversary.
Held scientific and technological training on green development of the potato industry
In recent years, due to the impact of successive winter and spring droughts, the potato sown area has been reduced, but it has remained about 900,000 mu, with a total output of 1.25 million tons and a comprehensive output value of 1.5 billion yuan, and the potato industry has played a vital role in The rural economic development and poverty alleviation in Xuanwei.
Xuanwei Municipal Party Committee and Municipal Government attach great importance to the development of the potato industry, since 2011, multi-party financing of more than 75 million yuan, built the largest potato detoxification seed potato production base in southwest China, with an annual output of 5 million tissue seedlings and 30 million miniature potatoes. It has introduced and cultivated three leading potato processing enterprises, such as Yunnan Yundian Starch Co., Ltd., which has an annual output of 30,000 tons of refined starch, Xuanwei Colorful Companion Food Co., Ltd., which has an annual output of 10,000 tons of potato chips, and Yunnan Nenya Agricultural Technology Co., Ltd., which has an annual output of 30,000 tons of quick-frozen potato blocks, and processes more than 400,000 tons of potatoes per year.

Since the establishment of the national potato industry technology system in 2008, Xuanwei City Potato Seed Potato R&D Center, as the supporting unit of Qujing Comprehensive Experimental Station, has bred 10 new potato varieties, Xuanshu 2, 4, 5, 6, 7, Yunshu 801, etc. passed the approval of crop varieties in Yunnan Province, Xuanshu No. 8 was registered as a new national crop variety last year, Xuanshu No. 2 was included in the national main variety by the Ministry of Agriculture and Rural Affairs in 2013, and Xuanshu No. 6 was included in the province's main recommended varieties by the Provincial Department of Agriculture and Rural Affairs in 2019; New technologies such as potato high ridge double-row membrane rain-resistant cultivation and drought-resistant cultivation after flat sowing have played an important role in local potato drought resistance and disaster reduction, and the maximum yield of "side membrane rain collection and drought-resistant cultivation" in drought years has reached 4595 kg, and the maximum yield of "drip irrigation + water and fertilizer integration" technology introduced and demonstrated this year has reached 5067 kg; the comprehensive prevention and control technology of potato late blight has been popularized and applied locally, with an annual average of more than 200,000 mu and a yield loss of more than 20%. Successfully introduced the small potato planting machine, harvester, grader, etc. developed by the national potato industry system, introduced and demonstrated the technical equipment such as unmanned aerial vehicle flight defense, provided important technical support for the mechanized production of local potatoes throughout the process; built and improved the 10,000 square meters potato "fog cultivation method" detoxified seed potato production system, so that the annual production capacity of micro potatoes in Xuanwei City reached 30 million grains, laying a solid foundation for the promotion of local potato seeds.
Although the green development of Sherwin-Williams' potato industry has made remarkable achievements. However, the potato industry development in Xuanwei City and the people's urgent requirements for advanced technology of excellent varieties, compared with the international and domestic potato advanced production areas, there is still a big gap in terms of output, industrial development quality, etc., there is still a huge space for innovation and development, Xuanwei City will be the state, Yunnan Province, Qujing City potato experts and scholars gathered in Xuanwei, for the potato industry to become stronger and bigger Pulse consultation as an opportunity, to fully promote the potato industry's technological innovation, new variety research and development, seed potato standardization production and green development, Let the potato industry play a greater role in boosting Theravi's rural economic development and leading rural revitalization.
